Tooth Sensitivity, Bleaching Efficacy, and Quality of Life in Young People and Adults: A Stratified, Randomized Bi‐Center Study

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study compared tooth sensitivity, bleaching efficacy, and the impact on oral health‐related quality of life between at‐home and in‐office tooth bleaching in adults and young individuals. Materials and Methods Eighty participants, 40 young people (14–20 years) and 40 adults (40–60 years), were randomly assigned to receive either

Reliability of Three Image‐Based Instrumental Color‐Measurement Methods

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To compare the precision of three clinically applicable, image‐based color assessment methods—smartphone imaging, a clinical colorimeter (Optishade), and a digital scanning device (Borea Cobra)—against a benchtop spectrophotometer for measuring CIELAB coordinates and CIEDE2000 (ΔE00) color differences of composite resin shades ...

Redefinition of Stemonosudis intermedia (Ege, 1933) and description of a new species from the western Atlantic Ocean (Aulopiformes: Paralepididae)

open access: yesJournal of Fish Biology, EarlyView.
Abstract We examined specimens of slender barracudina in the genus Stemonosudis collected from the western Atlantic Ocean. Investigation revealed that seven specimens represent the first adult records of Stemonosudis intermedia (Ege, 1933), previously known only from juveniles. We redescribed S.

Isolated in the highlands, found in the museum: A new species of Characidium (Crenuchidae) from a Bolivian National Park, with a CT scan revealing features

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from a small, isolated river in the highland areas of Noel Kempff Mercado National Park, Bolivia. The new taxon can be diagnosed by the presence of a relatively broad and conspicuous dark midlateral stripe extending from the tip of snout to the base of the caudal fin, markedly darker than the vertical ...

Enhanced exonuclease–Cas9 systems promote multiple nucleotide deletions with higher efficiency and broader targeting scope in plants

open access: yesJournal of Integrative Plant Biology, EarlyView.
Cas9 preferentially generates small indels. By tethering an exonuclease and a DNA‐binding domain (DBD) to Cas9, the Exo‐DBD‐Cas9 system efficiently promotes multiple nucleotide deletions. These expanded deletions enable effective disruption of miRNA‐mediated regulation and relieve translational repression through targeted editing of 3′ untranslated ...

Deep learning assisted high‐resolution microscopy image processing for phase segmentation in functional composite materials

open access: yesJournal of Microscopy, EarlyView.
Abstract In the domain of battery research, the processing of high‐resolution microscopy images is a challenging task, as it involves dealing with complex images and requires a prior understanding of the components involved. The utilisation of deep learning methodologies for image analysis has attracted considerable interest in recent years, with ...

CryoFluorSEM – A new approach for fluorescence and EM imaging of cryofractured plant samples

open access: yesJournal of Microscopy, EarlyView.
Abstract Cryo‐scanning electron microscopy (CryoSEM) permits the preparation and detailed imaging of bulky samples while keeping them in a hydrated state. For plant biology, cryofractures give information on cell ultrastructure and tissue organisation within a much larger context that is the whole organ or organism.

Cyclin‐dependent kinase 13 is indispensable for normal mouse heart development

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 616-630, April 2025.
Congenital heart disease (CHD) is the most common defect in live births. The role of cyclin‐dependent kinase (CDK13) in cardiogenesis and CHD was studied using a transgenic mouse model (Cdk13tm1b) carrying deletion of exons 3 and 4, causing loss of function.

A novel, PCP‐dependent tissue organising principle coordinating morphogenesis between embryonic skin epidermal layers

open access: yesJournal of Anatomy, EarlyView.
‘Outside‐in’ expression of Fz6 across multiple layers of mouse embryo epidermis is connected to Fz6 asymmetry in the basal layer plane. Fz6 loss‐of‐function correlated with failure to: coordinate axial bias of cell long axis orientation across epidermal layers, switch axial cell long axis orientation during suprabasal layer development and establish ...

Development of the abdominal musculature in the chicken embryo

open access: yesJournal of Anatomy, EarlyView.
In this study, we investigate anatomy, morphogenesis, segmental origin, and fiber formation of the abdominal musculature in the chicken embryo. We show that abdominal muscles arise from somites 24 to 28, and that the segmental identity of individual fibers in the abdominal muscle sheets is maintained.
